Underwater electromechanical release device driven by two-stage force-amplifier

Abstract

The invention discloses an underwater electromechanical release device driven by a two-stage force-amplifier. The underwater electromechanical release device is characterized in that when the underwater electromechanical release device works, a power source drives a worm wheel to rotate through a worm, the worm wheel drives a nut shaft to rotate through key connection, the nut shaft pushes a plugsleeve fixed on a shoulder joint of a mechanical arm to move downwards through a threaded pair inside the nut shaft, meanwhile, a socket sleeve is driven to slide downwards in a sealing sleeve, the nut shaft loses the suspension constraint on the plug sleeve when the plug sleeve moves to the end of the threaded pair, meanwhile, the plug sleeve and the sealing sleeve are unsealed, the mechanical arm is separated from an underwater robot under the action of gravity, and electromechanical release is completed. According to the underwater electromechanical release device, a worm wheel and worm pair and a lead screw and nut pair are connected in series to achieve two-stage force amplifying and self-locking, the release action required smaller power, and the self-locking connection is reliable;and the underwater electromechanical release device is suitable for underwater operation robots and can also be applied to other underwater electromechanical equipment.

Description

technical field [0001] The invention relates to the field of underwater operating robots, in particular to an underwater electromechanical release device suitable for separating an underwater robot from an underwater manipulator. Background technique [0002] With the rapid development of the modern economy, energy consumption is accelerating, and land resources are becoming increasingly scarce. More and more countries are turning their attention to the ocean, and the development and utilization of the ocean cannot be separated from various types of water Get off the robot. Underwater robots work in complex ocean environments, and their own safety faces various threats. During the operation of the underwater robot, its equipped manipulator may be entangled by aquatic plants, fishing nets, cables or stuck by underwater stones and cannot float up. At this time, quickly releasing the manipulator is the only way for the underwater robot to save itself. Since the manipulator ne...
